I have canvas app that has 3 column layout.One of the field is a people picker field an dit is behaving as below.
When user selects 2 people then then it properly displays the display names delimited by comma.
When user selcts 3 people where the people display names are a bit samll , it again adjusts to display the names properly.
But, when user selects 3 person (display names are a bit bigger) or more than 3 person , the the field display the number of itesm selected that means it displays as 3 items, 4 items like this instead of names.
